New Research Confirms Neurotoxicity of Pesticide Synergist PBO

(Beyond Pesticides, June 15, 2012) Researchers at the Duke University School of Medicine have developed a laboratory screening system for detecting neurotoxic chemicals and successfully tested it on more than 1,400 potential toxicants. The study confirms the high toxic activity of the chemical piperonyl butoxide (PBO), a chemical “synergist” used to increase the potency of […]

The study’s results indicate that most floors in occupied homes in the U.S. have measurable levels of insecticides that serve as sources of exposure to home dwellers. These persistent residues continue to expose people, especially vulnerable […]
